目的探讨会阴超声探测宫颈形态学指标对足月初产妇临产时间及分娩方式的预测效果。方法 120例孕妇应用会阴超声探测和妇科指检法对其宫颈形态学变化进行Bishop评分,分析孕妇的临产时间及分娩方式,将其预测结果与产妇实际的临产时间及分娩方式进行比较分析。结果产妇宫颈长度、内口开大程度等指标是临产时间的影响因素,120例产妇的会阴超声预测结果均与实际临床时间及分娩方式一致性很好,有118例与实际结果完全吻合,准确率达98.3%。结论会阴超声检查方法简单直观,便于操作,对产妇的刺激小,较少引起孕妇不适感;比传统的Bishop评分更具有优势,对足月初产妇的临产时间及分娩方式有较为准确的提示作用,值得临床上推广应用。
Objective To investigate the predictive effect of perineal ultrasonography on cervical morphological parameters of term full-term primipara and the mode of delivery. Methods 120 cases of pregnant women with perineal ultrasound and gynecological fingering test of cervical morphological changes Bishop score, analysis of pregnant women, labor hours and delivery methods, and its prediction results with the actual maternal labor time and mode of delivery were compared. Results The length of maternal cervix and the degree of internal opening were the influencing factors of labor time. The predictive value of perineal ultrasound in 120 maternal women was consistent with the actual clinical time and mode of delivery. 118 patients were in good agreement with the actual results Rate of 98.3%. Conclusion The method of perineal ultrasonography is simple and intuitive, easy to operate, less irritating to mothers and less uncomfortable to pregnant women. It has more advantages than the traditional Bishop score and has a more accurate prompt effect on term labor and delivery mode of full-term primipara. Worth clinical application.
